    Is this some Acrobat functionality or something?

    Off the top of my head, there’s pdfjam, pdftk and imagemagick (don’t forget the --dpi switch) who could probably do that, after reading the man pages. Or ghostscript’ gs, if you want to go in-depth.

    But generally, just rotate the source material you’ve got the pdf from. That’s how it is intended.

      I’ve used ghostscript a few times to reduce the quality of images within a pdf, so they wouldn’t be freezing my phone while reading. From ~80mb to 25mb

      The folks at Corvus Belli could learn a thing or two about that when making the pdfs for their Warcrow game (the core rules pdf is 118MB for 60 pages)
